The common use it is still a metal valve, but with the development, the metal valve is limited by external factors,ceramic valves have gradually come to the market.
Ceramic valves are made of high-purity ceramic materials, usually with materials are alumina ceramic , silicon carbide ceramic and silicon nitride ceramic. These materials have excellent abrasion and corrosion resistance, and are able to operate stably for a long time in harsh working environments. In addition, the ceramic valve also has excellent sealing performance and high temperature resistance, and can adapt to the working environment of high pressure and high temperature.
The advantages:
1. They have excellent wear resistance and are able to operate in high-speed fluids for long periods of time without damage.
2. It has excellent corrosion resistance. It can operate stably in acid and alkali corrosive media.
3. It has good sealing performance and high temperature resistance. It can operate safely and reliably in a high-pressure and high-temperature working environment.
